Worked on the cprabha/featureprofiles repository to enhance IS-IS protocol test configuration, focusing on improving multi-adjacency test flexibility and reliability. Introduced a deviation flag for interface reference ID format within the test metadata, enabling more robust and reproducible IS-IS testing scenarios. Collaborated closely with other contributors to ensure compatibility with isisRT2.18 updates, aligning new features with evolving protocol requirements. Leveraged skills in networking, protocol testing, and test automation, utilizing protobuf to structure and manage test metadata. The work addressed the need for configurable and scalable test environments, supporting more comprehensive protocol validation without introducing new bug fixes during this period.
